There are 3 major issues, as I see it, that must be staked out by judicial means, so that future legislators cannot interfere with our rights, before even thinking about the Hughes amendment.
1. The cases must be established that protect the right to arms (and ammunition). Keeping and bearing arms must be recognized beyond the threshold of the home.
2. The right must be expanded beyond mere self-protection/defense, to include the various sporting uses - of what use is the keeping and bearing, if you cannot practice proficiency?
3. The "list" of lawful arms must be established. So called "assault weapons" must be established as normal and usual firearms, in order to challenge the various assault weapons bans in several States.
This is just my take on what's going on with the current litigation strategy. I'm no lawyer, so take that for what it's worth!
